Individual Tree Crown Delineation Method Based on Multi-Criteria Graph Using Geometric and Spectral Information: Application to Several Temperate Forest Sites

Individual tree crown (ITC) delineation in temperate forests is challenging owing to the presence of broadleaved species with overlapping crowns. Mixed coniferous/deciduous characteristics that differ type thus require a flexible method delineation. The ITC based on multi-criteria graph (MCG-Tree) addresses this problem monospecific or mixed by combining geometric and spectral information. was used segment trees three forest sites different (tree types, distribution, planted natural forest). Compared state-of-the-art watershed segmentation approach, our increased performance up 25%. Our results showed main criterion improve quality related radius (performance improvement around 8%). Coniferous/deciduous classification automatically adapts MCG-Tree criteria tree. Promising are then obtained for forests.
